b20 into '90 si crx

I was wondering how hard it would be to swap a b20 into a '90 si crx. What problems I would run into, estimate of how much i would cost, etc. etc. If there would be any problems with wiring and tranny hook up and what not. Thanks in advance.

try the search feature, this has been discussed 45674873834 times before, i believe there is even links to pages all about b20 swaps on the articles section, but basically it will be the same as anyother b-series, but search before you ask!
